Built to M42 cobalt steel grade, it carries a 135-degree split point that reduces walking on entry and lowers the thrust force needed to start the hole. A gold oxide coating adds surface hardness and helps resist heat buildup during extended drilling cycles. At 1.57 inches overall length and 1.4 mm diameter, this bit fits standard chucks and collets used in machining, fabrication, and maintenance applications. Right-hand spiral flutes with a regular helix clear chips efficiently and suit a wide range of production and repair drilling tasks.\u003c\/p\u003e\u003cp\u003eThe C70061 is suited for drilling aluminum as its primary workpiece material, though the M42 cobalt construction also handles stainless steel, alloy steel, and other demanding materials common in metalworking and fabrication shops. It sees use in production drilling on CNC and manual drill presses, hand-held power drill applications, and maintenance repair work where small-diameter precision holes are required. The NAS 907 Type J specification makes it a known-standard part for aerospace and industrial procurement. Sold individually, but the minimum order quantity from the supplier is 12 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heavy-duty drilling performance in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eGold oxide coating improves surface hardness and heat resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces cutting resistance at the tip\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for aerospace and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for applications requiring a 1.4 mm diameter jobber length bit conforming to NAS 907 Type J.

Confirm the spindle is fully stopped and the machine is de-energized or locked out before changing bits. Secure the workpiece firmly before drilling to prevent movement that can snap small-diameter bits. Do not exceed the drill press or machine spindle speed rating recommended for the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.4 mm (0.0551 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.709 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.8661 inches (22 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2213\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694103396658,"sku":"C70061","price":66.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_5b0f49b3-9ed2-4dc4-8484-c5b05b4a605e.jpg?v=1788320286","url":"https:\/\/voomisupply.com\/products\/cleveland-c70061-cobalt-jobber-drill-bit-1-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
